Being a parent comes with many responsibilities. Beyond keeping your child happy, ensuring their health and proper growth is one of the most important tasks you have. Monitoring your child’s development doesn’t only mean addressing illnesses; it also means making sure they are growing and reaching milestones at the right pace. While it can feel overwhelming, there are simple ways to track your child’s growth and development to ensure they are heading in a healthy, strong direction.

Height and weight

Key measurements for assessing child development include height, weight, body mass index (BMI), and head circumference. These anthropometric measurements are a reliable and non-invasive way to monitor growth. Children generally grow in predictable patterns, and standardized reference charts are used worldwide to identify healthy development. Measurements below the 3rd percentile or above the 97th percentile can signal the need for further evaluation.

Boys

Age 3rd percentile 50th percentile  97th percentile 
6 months  ~6.0 kg and ~63 cm ~7.9 kg and ~67.5 cm ~9.8 kg and ~72 cm
12 months ~7.7 kg and ~71 cm ~9.6 kg and ~76 cm ~11.8 kg and ~80 cm
2 years ~10.5 kg and ~82 cm ~12.5 kg and ~87 cm ~15.5 kg and ~92 cm
5 years ~14 kg and ~100 cm ~18 kg and ~110 cm ~24 kg and ~118 cm
10 years  ~24 kg and ~125 cm ~32 kg and ~138 cm ~45 kg and ~150 cm
15 years ~45 kg and ~155 cm ~60 kg and ~170 cm ~80 kg and ~185 cm

Girls

Age 3rd percentile 50th percentile  97th percentile 
6 months  ~5.5 kg and ~61.5 cm ~7.3 kg and ~65.5 cm ~9.2 kg and ~70 cm
12 months ~7.0 kg and ~69 cm ~8.9 kg and ~74 cm ~11.5 kg and ~79 cm
2 years ~10.0 kg and ~81 cm ~12.0 kg and ~86 cm ~15.0 kg and ~91 cm
5 years ~13.5 kg and ~99 cm ~17.5 kg and ~109 cm ~24 kg and ~117 cm
10 years  ~24 kg and ~125 cm ~33 kg and ~138 cm ~47 kg and ~152 cm
15 years ~42 kg and ~150 cm ~55 kg and ~163 cm ~75 kg and ~175 cm

Note: The height and weight reference values are sourced from the World Health Organization (WHO): https://www.who.int/tools/child-growth-standards/standards/. Please keep in mind that reference values may vary depending on the geographic region and should always be used and interpreted according to the specific population.

‘While height and weight charts are a useful guide, individual growth can vary widely. Measurements outside the average range do not automatically indicate a problem. For reliable assessment, it’s always best to discuss your child’s growth with a pediatrician,’ advises our pediatrician Dr Marija.

Infants up to 2 years should have their height and weight measured at primary healthcare centers on a digital scale in a lying position for accurate results.

Nutrition

Proper nutrition is essential for healthy growth and development, especially during the first years of life. Key points for parents include the following:

  • Breastfeeding is recommended for at least the first year. If breastfeeding is not possible, modified infant formula (not regular cow’s milk) is advised.
  • Introduction of solid foods should begin no earlier than 4 months. Introduce new foods one at a time every three days to monitor for potential allergies. Start with easily digestible carbohydrates.
  • Gradually introduce a variety of foods up to 2 years, with eggs (first the yolk and then the eggwhites) and meat added last. Nuts and berries should be avoided until after 5 years.

Ensuring your child receives adequate nutrients is crucial for long-term health. You can learn more about balanced nutrition in our blog “Know Your ABCs”.

Cognitive and motor development

Monitoring cognitive and motor milestones is equally important. Some key developmental markers include the following.

Infants:

  • 1–2 months: can lift head independently
  • 4 months: responds to sounds and noise
  • 6 months: able to sit with support
  • 6–9 months: begins crawling
  • 1 year: first steps

Toddlers and older children:

  • Observe responses to visual and auditory stimuli to ensure healthy vision and hearing.
  • From ages 9 to 12 years, monitor musculoskeletal development, including the spine. Early detection of scoliosis or kyphosis allows for timely intervention.
  • Pectus carinatum (“chicken breast”), common in children in this age group, is the protrusion of the chest outward, and can improve with activities like swimming.
  • Monitor for flat feet, which can be corrected through exercises, walking on sand, or encouraging yoga-style sitting positions, as well as wearing special padded shoes.

Cognitive and social development is equally important. Encourage outdoor play, social interaction, creative activities, and sports. Limit screen time to under 2 hours per day, and avoid screens at least 2 hours before bedtime to protect sleep quality and overall development.

Routine health checks

Even with attentive monitoring at home, regular pediatric check-ups are vital. Standard visits occur in the first months after birth and at ages 2, 4, 7, 8, 10, 12, 14, 16 and 18 years. The official vaccination schedule should also be followed, including vaccines at birth, 1 month, 2 months, 3 months, 4 months, 6 months, 2 years, 7 years and 14 years.

Keeping track of your child’s growth and developmental milestones is essential, but regular consultations with a pediatrician provide the most accurate insights. In today’s world, misinformation about child health is easy to find online, making professional guidance more important than ever.
